Description

Technical Field

[0001] This utility model relates to the field of sports rehabilitation and personal care equipment technology, and in particular to a fascia gun with high-frequency vibration atomization. Background Technology

[0002] As a common sports rehabilitation device, the fascia gun uses an internal motor to drive an eccentric mechanism, generating high-frequency mechanical impact that directly targets the deep muscle fascia, effectively promoting blood circulation and relieving muscle soreness and stiffness. With increasingly diverse personal health care needs, users are not only focusing on deep muscle relaxation but also demanding more soothing care for the skin's surface and efficient absorption of post-workout skincare products.

[0003] However, existing fascia gun products have relatively simple functional designs, mostly focusing only on mechanical striking. Their massage heads are usually made of solid rubber or hard plastic. While they can meet basic muscle relaxation needs, they cannot provide delicate care for the skin's surface, nor do they have skincare product delivery capabilities. Users who want to perform skincare often need to purchase separate ultrasonic delivery devices or atomizing equipment, which not only increases economic costs but also brings considerable inconvenience to daily use due to the multiple devices they carry.

[0004] Therefore, this invention proposes a fascia gun with high-frequency vibration atomization to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, ordinary fascia guns have only one function, which can only provide deep mechanical impact and cannot take into account the skin surface care and skin care product atomization and delivery. As a result, users need to purchase multiple devices, which are inconvenient to carry and have high operating costs. The present invention aims to provide a fascia gun with high-frequency vibration atomization that has an improved structure and can effectively solve the above problems.

[0006] This utility model provides a fascia gun with high-frequency vibration atomization, including: a fascia gun body, and a metal massage head, a high-frequency module, a drive board, a main control board, a power supply, a motor, an eccentric wheel, and a connecting rod piston shaft assembly disposed inside the fascia gun body.

[0007] The motor is fixedly installed in the body of the fascia gun, and its output end is fixedly connected to the eccentric wheel. The eccentric wheel is rotatably connected to one end of the connecting rod piston shaft assembly, and the other end of the connecting rod piston shaft assembly extends outward. The high-frequency module has a flat shape and is disposed on the inner surface of the metal massage head. The metal massage head, together with the connecting rod piston shaft assembly, securely clamps the high-frequency module between the two.

[0008] Furthermore, the drive board and the main control board are fixedly installed in the fascia gun body as the control core. The power supply is electrically connected to the main control board, the drive board is electrically connected to the main control board, the motor is electrically connected to the main control board, and the drive board is electrically connected to the high-frequency module. The outer surface of the fascia gun body is also provided with independent high-frequency atomization switch and massage switch. Both of these switches are electrically connected to the main control board, thereby realizing independent control of dual modes.

[0009] Preferably, the metal massage head has a protruding external thread structure on the side facing the connecting rod piston shaft assembly, and the end of the connecting rod piston shaft assembly has a size-matched internal thread structure. The high-frequency module is glued and fixed to the inner surface of the metal massage head. This structural design makes the three parts tightly connected, which can transmit both low-frequency impact and high-frequency vibration efficiently.

[0010] Preferably, to prevent loosening during severe vibration, the threaded connection between the metal massage head and the connecting rod piston shaft assembly is in a non-removable locked and fixed state. If necessary, adhesives or limit pins can be used for reinforcement to ensure the long-term stability of the structure.

[0011] Preferably, the high-frequency module contains a piezoelectric ceramic module, which is electrically connected to the drive board. The piezoelectric ceramic module generates micro-amplitude vibrations at ultrasonic frequencies under the drive of the high-frequency electrical signal from the drive board.

[0012] Preferably, the driver board and the main control board are designed as two physically independent circuit board structures to reduce electromagnetic interference. A signal connection line is provided between the driver board and the main control board. The main control board is configured to send start and stop control signals to the driver board to coordinate the operation of the whole machine.

[0013] Preferably, the high-frequency atomization switch and the massage switch are physically independent and located at different positions on the device body or on the same panel. The high-frequency atomization switch controls the on / off of the power supply circuit from the main control board to the high-frequency module, thereby enabling one-button activation or deactivation of the atomization function.

[0014] Preferably, the massage switch controls the on / off state of the motor drive signal sent from the main control board to the drive board, thereby controlling the start and stop of the motor. Users can use the massage function separately as needed.

[0015] Preferably, the eccentric wheel includes an eccentrically positioned shaft pin, and one end of the connecting rod piston shaft assembly is sleeved on the eccentric shaft via a bearing. The connecting rod piston shaft assembly converts the rotational motion of the eccentric wheel into the reciprocating linear motion of the metal massage head, thus realizing the conversion of power form.

[0016] Preferably, the power source is a built-in high-capacity rechargeable battery pack, which is located on one side of the drive board and the main control board, and provides stable power support for all electronic components of the whole machine.

[0017] Preferably, the metal massage head is made of stainless steel or aluminum alloy, which are metals that facilitate the conduction of sound waves. The surface of the metal massage head away from the high-frequency module is processed into a smooth plane or curved surface. This surface serves as an atomizing working surface for contacting the skin or liquid, and can effectively disperse the liquid into a mist.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing fascia guns only have a single deep-penetration function and cannot meet the user's needs for skin surface care and skin care product delivery by integrating a high-frequency module at the mechanical transmission end of the fascia gun and using a non-removable metal massage head. It achieves the dual effect of deep muscle mechanical impact relaxation and surface skin ultrasonic atomization care on the same handheld device, eliminating the need for users to purchase multiple devices and improving the portability and practicality of the product.

[0019] 2. This utility model solves the problems of easy loosening and falling off of traditional detachable massage head structures under the dual effects of high-frequency vibration and strong impact by coaxially clamping and fixing the high-frequency module between the connecting rod piston shaft assembly and the metal massage head with a threaded locking structure. It achieves the technical effect of ensuring both the rigid transmission of mechanical impact force and the lossless transmission of high-frequency vibration energy to the surface of the massage head, effectively extending the service life of the equipment.

[0020] 3. This utility model solves the problem of electromagnetic interference to the high-frequency signal generation circuit caused by the large current generated by the high-power motor during startup and operation by adopting a dual circuit board architecture with independent main control board and driver board and dual independent switch design. It achieves the technical effect of two working modes not interfering with each other, and can operate independently or synchronously, ensuring the stability of the high-frequency atomization function, while providing users with a flexible and convenient operating experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 This utility model provides a fascia gun with high-frequency vibration atomization, which aims to solve the problem that existing fascia guns only have a single mechanical impact function and cannot realize the atomization and delivery of skin care products and the soothing care of the surface skin, resulting in users having to purchase multiple devices separately.

[0025] This fascia gun with high-frequency vibration atomization includes a fascia gun body 1, which serves as the handheld housing and mounting base, and a metal massage head 2, a high-frequency module 5, a drive board 6, a main control board 7, a power supply 8, a motor 9, an eccentric wheel 10, and a connecting rod piston shaft assembly 11, all compactly housed inside the fascia gun body 1. The fascia gun body 1 houses and protects the internal components and provides a handle area for the user to grip. The motor 9, as the power source, is fixedly mounted in the upper part of the fascia gun body 1 by screws or brackets. The output shaft of the motor 9 engages with and is fixedly connected to the center hole of the eccentric wheel 10, allowing the eccentric wheel 10 to rotate synchronously with the motor 9. The eccentric wheel 10 has an eccentric shaft structure offset from the center of rotation. The shaft structure and one end of the connecting rod piston shaft assembly 11 are rotatably connected through a bearing, and the other end of the connecting rod piston shaft assembly 11 extends outward through the front opening of the fascia gun body 1, thereby converting the rotational motion output by the motor 9 into the reciprocating linear motion of the end of the connecting rod piston shaft assembly 11. In order to achieve dual functions, the high-frequency module 5 is set on the inner surface of the metal massage head 2. The metal massage head 2, as the execution component that directly contacts the human body, is connected to the end of the connecting rod piston shaft assembly 11, so that the high-frequency module 5, the metal massage head 2 and the connecting rod piston shaft assembly 11 form a linked whole component. While performing mechanical impact massage, the vibration energy generated by the high-frequency module 5 can also be directly transmitted to the metal massage head 2.

[0026] The high-frequency module 5 has a flat, disc-shaped shape and encapsulates a piezoelectric ceramic module inside. This piezoelectric ceramic module can generate mechanical vibrations in the ultrasonic frequency band under electrical signal excitation. The high-frequency module 5 is set on the inner surface of the metal massage head 2. In order to ensure the high strength of mechanical impact and the efficient transmission of ultrasonic waves, the metal massage head 2 has an integrally extended connecting post structure with external threads on the side facing the connecting rod piston shaft assembly 11. The end center of the connecting rod piston shaft assembly 11 is correspondingly provided with an internal threaded hole for matching. During assembly, the high-frequency module 5 is pasted and fixed to the inner surface of the metal massage head 2. By tightening the threads, the three are locked in a non-removable state. This rigid connection structure ensures that the low-frequency, large-stroke impact force generated by the motor 9 can drive the metal massage head 2 to strike deep muscles without loss through the connecting rod piston shaft assembly 11. At the same time, it also ensures that the high-frequency micro-amplitude vibration generated by the high-frequency module 5 can be directly transmitted to the atomizing working surface of the metal massage head 2 away from the connecting rod piston shaft assembly 11.

[0027] Meanwhile, in order to achieve independent and precise control of the motor 9 and the high-frequency module 5, the fascia gun body 1 is internally equipped with an independent drive board 6 and a main control board 7. The power supply 8 is located on the back side or adjacent area of ​​these two circuit boards and provides them with power. The drive board 6 integrates high-power driving devices, which are specifically used to receive control signals and drive the motor 9 to operate. The main control board 7 integrates a logic control chip and a high-frequency signal generation circuit. The main control board 7 establishes a communication connection with the drive board 6 through a signal connection line or a board-to-board connector. The main control board 7 is configured to send start and stop commands to the drive board 6 and directly output high-frequency AC drive signals to the high-frequency module 5. This dual-board separation design effectively isolates the large current interference when the motor 9 is working and ensures the stability of the high-frequency atomization function.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to facilitate intuitive and convenient user control of the two different working modes, the outer surface of the fascia gun body 1 is provided with mounting holes, on which a high-frequency atomization switch 3 and a massage switch 4 are respectively provided. These two switches are independent of each other and are both electrically connected to the main control board 7. The high-frequency atomization switch 3 is configured to send a high-frequency mode on or off signal to the main control board 7, thereby controlling the on / off of the power supply circuit from the main control board 7 to the high-frequency module 5. The massage switch 4 is configured to send a massage mode on or off signal to the main control board 7. The main control board 7 controls the on / off of the motor 9 drive signal sent to the drive board 6 accordingly, thereby realizing independent control of the start and stop of the motor 9.

[0029] As another preferred embodiment, in order to ensure atomization effect and durability, the metal massage head 2 is made of a metal material that is conducive to ultrasonic wave conduction and corrosion resistance. The surface of the side away from the high-frequency module 5 is processed into a smooth plane or a slightly convex curved surface. This surface constitutes the atomization working surface. When this surface comes into contact with liquid, the high-frequency vibration energy can make the liquid atomize quickly. At the same time, the metal material can also withstand the mechanical stress during impact massage.

[0030] As a further preferred embodiment, in order to optimize the use of internal space and ensure stable power supply, the power supply 8 is selected from a high-capacity rechargeable lithium battery pack. Its external dimensions are adapted to the internal cavity where the drive board 6 and the main control board 7 are located. The power supply 8 is fixedly installed on one side of the drive board 6 and the main control board 7, and is connected to the power input terminal of the main control board 7 and the drive board 6 through wires or contacts. The bottom of the power supply 8 also integrates a charging interface, which is exposed at the bottom of the fascia gun body 1 for the convenience of the user to perform charging operations.

[0031] The working principle of this utility model's fascia gun with high-frequency vibration atomization is as follows: When a user needs to perform deep muscle relaxation, they press the massage switch 4. After receiving the activation signal, the main control board 7 controls the drive board 6 to conduct the power supply circuit of the motor 9. The motor 9 starts to run at high speed and drives the eccentric wheel 10 to rotate. The connecting rod piston shaft assembly 11 converts the rotational motion into reciprocating linear motion under the drive of the eccentric wheel 10. The connecting rod piston shaft assembly 11 drives the high-frequency module 5 and the metal massage head 2 at the end to perform reciprocating impact motion in sync. The metal massage head 2 acts directly on the human muscle tissue and achieves the effect of deep fascia relaxation through physical impact.

[0032] When a user needs to apply skincare products or perform surface skin care, pressing the high-frequency atomization switch 3 causes the main control board 7 to directly output a high-frequency AC signal to the high-frequency module 5. The piezoelectric ceramic module within the high-frequency module 5 then generates high-speed reciprocating stretching and contracting vibrations at ultrasonic frequencies. This vibrational energy is transmitted to the metal massage head 2 through a tightly fixed connection interface. If skincare liquid is applied to the surface of the metal massage head 2, the high-frequency vibrations will rapidly atomize the liquid into tiny particles. If the metal massage head 2 is placed against the skin, the high-frequency vibrations will promote the opening of skin pores and aid in the absorption of skincare products, thus achieving a beauty care function. Users can activate either of these modes individually or simultaneously, depending on their needs. During this process, the metal massage head 2 performs low-frequency, large-stroke reciprocating motion while simultaneously maintaining high-frequency, micro-amplitude vibrations, achieving a dual care effect.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
